Objective: To evaluate the casuistry of vascular malformations in our division and to analyze the predominant clinical findings of these malformations. Methods: A survey was carried out searching for all cases of pulmonary vascular malformations diagnosed, from August 1986 to December 2003. Through the analysis of the medical records of these patients, the following variables were evaluated: structural pulmonary alteration, clinical presentation, mean age at diagnosis, gender and clinical evolution. Results: The pathologies found were: pulmonary sequestration 6 cases (25%), agenesis and / or pulmonary hypoplasia 7 cases (30%), arteriovenous fistulas 4 cases (16%), vascular ring 6 cases (25%) and pulmonary valve agenesis 1 case (4%). Nine patients were male and 13 were female. Age at diagnosis ranged from 1 month to 58 years. The symptoms varied according to the pathology. The most frequent were recurrent respiratory infection, stridor, cyanosis, dyspnea. Of the 22 patients studied, 11 (50%) cases were amenable to surgical correction. Conclusion: Pulmonary vascular malformations are rare pathologies, but pediatricians should keep them in mind to obtain an early diagnosis, correct propaedeutics and, if possible, surgical correction of these pathologies.

As plantas necessitam de elementos essenciais para sua vida, devido as diversas funcoes que esses elementos desempenham.  descrever e avaliar os sintomas de carencia nutricional de macronutrientes em abobrinhaa italiana, atraves do diagnostico visual e avaliar os parâmetros de crescimento. O delineamento estatistico utilizado foi o DIC com tres repeticoes, contendo 7 tratamentos, em solucao nutritiva. Os tratamentos foram: solucao nutritiva completa (controle), solucoes nutritivas com omissoes individuais de N, P, K, Ca, Mg e S. Apos germinadas, as mudas foram translocas para a solucao nutritiva completa, com 10% da sua forca ionica (periodo de adaptacao), as quais permaneceram sob aeracao constante. Posteriormente, foram transplantadas em vasos de plastico (8L) com solucao nutritiva. Os sintomas percebidos, foram fotografados e descritos. Apos a manifestacao dos sintomas visuais de deficiencia, as plantas dos tratamentos foram colhidos. A omissao dos nutrientes N, P, K, Ca e Mg em solucao nutritiva resultam em alteracoes morfologicas, traduzidas em sintomas caracteristicos de deficiencia de cada nutriente. A omissao de macronutrientes afeta os parâmetros de crescimento e producao de materia seca de Abobrinha italiana. De maneira em geral, a omissao de macronutrientes que mais afeta as diferentes partes a plantas foram N e P.
